The utility model discloses a kind of bolts.Including integrally formed bolt head and screw rod, interior hexagonal counterbore is provided on the bolt head, limiting plate is slidably connected in the interior hexagonal counterbore, No.1 spring is provided on the limiting plate bottom surface, the No.1 spring is connected with the interior hexagonal counterbore bottom surface, simultaneously, groove body is opened up on the bolt head, the waist hole connected with the groove body is offered on the interior hexagonal counterbore inner wall, gag lever post is rotatably connected in the groove body, several double wedges are provided on the gag lever post, and the buckling groove with double wedge cooperation is offered on the limiting plate.The utility model in interior hexagonal counterbore by setting multigroup position limiting structure, the operable region of hexagonal counterbore in limitation, so as to make hexagonal counterbore whole abrasion deformation in entire in misoperation, provides fault tolerant workspace, extends bolt service life.
Description
Technical field
The utility model is related to technical field of fastening, especially a kind of bolt.
Background technology
The bolt of interior hexagonal counterbore is common fastener, in routine use, because of misoperation or cooperating equipment
Size and the size of interior hexagonal counterbore are not inconsistent, and cause interior hexagonal counterbore abrasion deformation, and ultimately resulting in bolt can not normal mounting report
It gives up or can not be taken out after installing, therefore, need to design certain structure in face of this kind of problem to solve.
Utility model content
The utility model is directed to deficiency of the prior art, a kind of bolt is provided, by being set in interior hexagonal counterbore
Put multigroup position limiting structure, the operable region of hexagonal counterbore in limitation, so as to which hexagonal in entire will not be made to sink in misoperation
Hole whole abrasion deformation provides fault tolerant workspace, extends bolt service life.
In order to solve the above technical problems, the utility model is addressed by following technical proposals：A kind of bolt, including one
Body formed bolt head and screw rod is provided with interior hexagonal counterbore on the bolt head, is slidably connected in the interior hexagonal counterbore
Limiting plate, No.1 spring is provided on the limiting plate bottom surface, and the No.1 spring connects with the interior hexagonal counterbore bottom surface
It connects, meanwhile, groove body is opened up on the bolt head, the waist connected with the groove body is offered on the interior hexagonal counterbore inner wall
Hole is rotatably connected to gag lever post in the groove body, several double wedges is provided on the gag lever post, and are opened up on the limiting plate
There is the buckling groove with double wedge cooperation.
The beneficial effects of the utility model are：The utility model by setting multigroup position limiting structure in interior hexagonal counterbore,
The operable region of hexagonal counterbore in limitation, so as to which hexagonal counterbore whole abrasion deformation in entire will not be made in misoperation,
Fault tolerant workspace is provided, extends bolt service life.
Description of the drawings
Fig. 1 is the utility model schematic cross-section.
Fig. 2 is the enlarged diagram at D in Fig. 1.
Specific embodiment
The utility model is described in further detail with specific embodiment below in conjunction with the accompanying drawings：Referring to Fig. 1 and Fig. 2,
A kind of bolt including integrally formed bolt head 1 and screw rod 2, is provided with interior hexagonal counterbore 3 on the bolt head 1, it is described in six
Limiting plate 4 is slidably connected in angle counterbore 3, No.1 spring 5, the No.1 spring 5 and institute are provided on 4 bottom surface of limiting plate
Interior 3 bottom surface of hexagonal counterbore connection is stated, meanwhile, groove body 11, interior 3 inner wall of hexagonal counterbore are opened up on the bolt head 1
On offer the waist hole connected with the groove body 11, gag lever post 6 is rotatably connected in the groove body 11, is set on the gag lever post 6
Several double wedges 61 are equipped with, and the buckling groove 41 with the double wedge 61 cooperation is offered on the limiting plate 4.
By the cooperation of the buckling groove on the double wedge and limiting plate on gag lever post, ensure that limiting plate is limited in setting position
Place, after the part being located in interior hexagonal counterbore above limiting plate is worn, rotary stopper bar so that double wedge and buckling groove point
From, then limiting plate pushed into a distance and then negative direction rotary stopper bar so that corresponding double wedge coordinates with buckling groove
Clamping, limiting plate is limited at the position, in this way, can multiple circulate operation.
Above example is only to illustrate the technical solution of the utility model, rather than its limitations；Although with reference to foregoing reality
Example is applied the utility model is described in detail, it will be understood by those of ordinary skill in the art that：It still can be to preceding
The technical solution recorded in each embodiment is stated to modify or carry out equivalent substitution to which part technical characteristic；And these
Modification is replaced, and the essence of appropriate technical solution is not made to depart from the spirit and model of various embodiments of the utility model technical solution
It encloses.
